Objectives: To identify relationships between vitamin D serum levels and the presence of autoantibodies directed against vitamin D and levels of interleukin(IL)-17 and IL-23 in patients with systemic lupus erythematosus (SLE). Methods: The study included 49 patients with SLE. Serum concentrations of 25(OH)D 3 were measured with electrochemiluminescence immunoassay (ECLIA). Enzyme-linked immunosorbent assays (ELISA) were used to determine antibodies directed against 1,25(OH) 2 D 3 and levels of IL-17 and IL-23 in serum of SLE patients. In evaluation of vitamin D status, the control group consisted of 49 age and gender matched healthy individuals, whereas in assessment of anti-vitamin D antibodies the control group comprised 30 sera from blood donors. Results: Serum concentration of 25(OH)D 3 in SLE patients during the warm season was 18.47 AE 9.14 ng/ml, which was significantly decreased as compared with that of the control group -31.27 AE 12.65 ng/ml (p ¼ 0.0005). During the cold season a trend toward lower concentration of 25(OH)D 3 in SLE patients was revealed; however, it did not reach statistical significance (11.71 AE 7.21 ng/ml vs. 16.01 AE 8.46 ng/ml; p ¼ 0.054). Results within the recommended range for vitamin D (30-80 ng/ml; 70-200 nmol/l) were observed only in three patients. The 25(OH)D 3 concentration was decreased in SLE patients with renal disease or leucopenia as compared with the levels in patients who did not have either problem (p ¼ 0.006 and p ¼ 0.047, respectively). The cold season was found to be a risk factor for vitamin D deficiency (<20 ng/ml) (odds ratio ¼ 9.25; p ¼ 0.005). Autoantibodies directed against 1,25(OH) 2 D 3 were detected in three SLE patients. No significant difference in 25(OH)D 3 serum concentrations was found between SLE patients with and without these autoantibodies. No link was shown between the existence of autoantibodies against 1,25(OH) 2 D 3 and clinical or laboratory findings, including IL-17 and IL-23 levels. However, serum concentrations of IL-23 were lower in patients with vitamin D deficiency (p ¼ 0.037). Conclusions: SLE patients, especially those with leucopenia or renal involvement, are at high risk of vitamin D deficiency and require vitamin D supplementation. Some SLE patient sera contained 1,25(OH) 2 D 3 antibodies, but these antibodies do not appear to affect vitamin D levels. Lupus (2012) 21, 477-484.

Cellulite (also known as gynoid lipodystrophy or orange peel syndrome) is one of the most common lipodystrophy syndromes, which affects millions of post-adolescent women. Cellulite is manifested by topographic disorders of subcutaneous tissue such as nodules, edema, and abnormal fibrosis. It is located mainly on the pelvic area, especially on the buttocks. Its pathogenesis is complexed and unclear. There are several theories about its pathophysiology. Hormonal disorders, endothelial dysfunction and genetic predispositions are taken under consideration.

VEGF could be regarded as a potentially important mediator in the pathogenesis of AD, as VEGF levels correlate somewhat with AD severity.

Physicians’ awareness about neuropsychiatric syndromes in systemic lupus erythematosus (SLE) is not rarely limited to seizures and psychoses included in the American College of Rheumatology (ACR) classification. Involvement of the central nervous system (CNS) with its rich symptomatology still belongs to the faintly recognised and understood aspects of lupus. The objective was to investigate prevalence and clinical correlations of psychiatric disorders in SLE patients. Fifty-two SLE patients were included. Disease duration and current and cumulative corticosteroid doses were calculated. Disease activity was assessed with the Systemic Lupus Activity Measure (SLAM). All subjects were examined by a psychiatrist. Psychiatric disorders were classified according to ACR criteria for neuropsychiatric systemic lupus erythematosus (NPSLE). Mini-Mental State Examination (MMSE) and Clock Drawing Test (CDT) were used to screen for cognitive impairments. Mental disorders were diagnosed in 16 (30.77%), depressive disorder in 6 (11.54%), cognitive dysfunction in 5 (9.62%), anxiety disorder in 4 (7.69%) and psychosis in one patient (1.92%). SLE duration was shorter in patients diagnosed with anxiety disorder (P < 0.05), and cumulative dose of corticosteroids was lower in patients with anxiety disorder (P < 0.01). There was high positive correlation between SLE duration and cumulative dose of corticosteroids (r = 0.684, P < 0.001). Shorter SLE duration in patients with anxiety disorder seems to reflect its adaptative nature.

As most studies on pemphigus vulgaris (PV) pathogenesis concern its active stage, we aimed to evaluate the serum concentration of TNF-α, IL-1, and IL-6 in PV patients in clinical remission. The study group consisted of sera from 19 PV patients in active stage and from 24 patients in clinical remission. 19 sera taken from healthy subjects served as the controls. Serum IL-6 concentrations in PV active and PV remission group were significantly higher when compared to the controls (P < .05). In patients in active stage of PV, a significant correlation between serum IL-1 and IL-6 concentrations was found (r P = 0.46; P < .05). We also found a negative correlation between TNF-α level and pemphigus antibodies titer in the patients from the remission group (r S = −0.47303; P < .02). Our data suggest that IL-6 and TNF-α may be involved in maintaining immunological disturbances in remission stage of PV.

The findings emphasize the importance of pruritus in the majority of psoriasis patients and its significant association with compromised quality of life, older age, greater psoriasis severity, and a specific pattern of psychological responses to stress.

The hormonally active form of vitamin D3, 1,25(OH)2D3 (calcitriol), exerts actions through VDR receptor, which acts as a transcriptional factor. Calcitriol is an immunomodulator that affects various immune cells, and several studies link it to many autoimmune diseases. BsmI polymorphism affects the level of VDR gene transcription, transcript stability, and posttranscriptional modifications. It seems to be related to the systemic lupus erythematosus (SLE). Our study examined the characteristics of VDR gene BsmI polymorphism in Polish SLE patients and their relationship with clinical manifestations of the disease. We genotyped 62 patients with SLE and 100 healthy controls using the real-time PCR. There were no differences observed in the frequency of BsmI genotypes in SLE patients and in the control group. There was no significant correlation between BsmI genotypes and clinical symptoms of SLE, but the AA genotype correlates with higher levels of antinuclear antibodies (ANA) in this group (r = 0.438; P = 0.002). A larger study examining BsmI and other VDR gene polymorphisms is needed. It may allow explaining differences in the clinical picture of the disease and choosing a personalized therapy.
